Reviews

Nice!

UPDATE - still worth 5 stars to me. Great for acidic loops. Easy export to AudioShare. Still like it! I'm giving it 5 stars right away because I found it so intuitive and easy to get some interesting results from. Compared to other similar apps it just seemed to click for me. I bought the IAP pretty quickly after trying it out. There's plenty more to explore but I'm already sold. I think they did a good job with this so far.

Ignore The Hate

RD4 is magnificent: one of the best workflows I've ever encountered for iOS music making and just the right balance of choice x limitation. The IAP is a bargain and the fact that one can have multiple 303 (or other) instances running simultaneously is a thing of pure beauty. RD4 sounds amazing as well and we're lucky to have it. Easy 5 stars.

Longest "Bait and Switch" Scheme Ever Run In App Store

Run from this app. The slim version is no longer worth the few seconds it takes to download. I've loved this app and have been using it regularly for a very long time—previously had my review at four stars—until this afternoon, when an automatic update removed all but one of its drum kits and many of its other features. Tapping restore does nothing to restore any of the elements I've been using without a problem for the entire time I've been using the app. I'm not sure why the developers felt it necessary to utterly neuter, and thus eliminate the possibility of enjoying, the user experience, but for anyone in the market for an app that's a versatile groovebox, drum machine, synth, etc., and you've heard good things about this one, ignore what you've heard. More important, though, can you really trust developers who decide without warning to take away features you've had and have been using for years in order to engage in a scheme to begin charging for them? In my view, absolutely not.

Link crashes app

Tapping Link crashes the app. In-app keys respond slow. Sequence fidgets while actively controlling things. 303 sounds aight I guess. Nice that they give a little bit fix.
